摘要
针对网络设备销售收入预测难度较大,建立最小二乘法和三点法两种不同模型进行预测与应用分析,能对时间序列数据呈现抛物线形状的实际问题进行有效预测。
According to the difficulty in forecasting the sales revenue of network equipment, the paper establishes the prediction and application analysis of two different models of least squares and three points method, which can effectively predict the practical problems of time series data presenting parabolic shape.
